Hi guys,
I have not been on here for a while but recently my 2001 x5 4.4i with 65,000 miles on it have a ses light the lit on. Its fustrating to see it. So i have borrowed my friend peake tool to see what was going wrong. It pull up OF which was the Pre Cat Oxygen Sensor. I am wondering, is it easy to install and where can i find instructions on how to install this mechanism. Also, While i use the peake tool i also reset the light this afternoon. It came on again tonight. I just notice the light came on last friday after i fill up the tank of gas and i also made sure i tighten the cap. I believe right now is the oxygen sensor. Thanks for all who help me and i love this forum. It help me save alot and enlighten my knowledge.
